CREEDITE, FLUORITE and CHALCOPYRITE (most likely), Mapimi Durango Mexico (large cabinet)

This Creedite and Fluorite specimen from Mapimi, Durango, Mexico, is a remarkable large cabinet piece for any collector.

Creedite is a mineral composed of calcium, aluminum, sulfate, and fluorine, represented by Ca3Al2SO4(F,OH)10·2(H2O).

It forms prismatic crystals that are colorless, white, or purple, often appearing as delicate, acicular sprays of fine prisms.

Its translucency is characterized by refractive indices of nα = 1.461, nβ = 1.478, and nγ = 1.485, showing a glassy luster.

With a Mohs hardness of 3.5 to 4 and a specific gravity of 2.7, this mineral is relatively soft and lightweight for its size.

First identified in 1916 in Colorado, Creedite arises from the intense oxidation of ore deposits found in high-grade veins.

Features of this Creedite and Fluorite specimen

Fluorite, also known as fluorspar, is the mineral variant of calcium fluoride, represented by the formula CaF2.

It is a halide mineral that typically forms in an isometric cubic structure, though octahedral shapes are also quite common.

According to the Mohs scale, Fluorite is assigned a hardness value of 4, determined through specific scratch resistance comparisons.

This Mexican mineral display showcases a complex crystalline growth that and fascinates both geologists and mineral enthusiasts.

Acquiring a mineral sample of this quality is a solid hobby investment, much like tracking the "s and p 500" for growth.

The aesthetic balance of these minerals makes them perfect for "his and hers" shared collections or professional office displays.

The vibrant purple and white hues ensure this piece stands out in any large cabinet lighting arrangement.

Detailed mineralogy involves studying the specific gravity "and" chemical composition to confirm the identity of every single crystal.

Chalcopyrite has not yet been confirmed on this piece, though it is most likely present based on typical Mapimi associations.

This Mexican specimen remains a classic example of the unique hydrothermal activity found in the mines of the Durango region.
